Answer:
2.10 s, 10.40 s.
Step-by-step explanation:
We know that the height of the rocket is given by the function:
We are asked to find the time for which the height of the rocket will be 350 ft. So, for that moment, we know the height but we don't know the time; however, we know that the equation can help us to find the time, doing h=350:
The last is a quadratic equation, which can be put in the form 
and solved applying the formula:
So, let's put the equation on the form adding 
and subtracting 
to each side of the equation; the result is:
So, we note that a=16, b=-200, and c=350.
Then,
According to the equation, that are the times for which the height will be 350 ft; that is because the rocket is going to ascend and then to fail again to the ground.
Each exterior angle of a regular 25-gon = 360/25 = 14.4 deg. and each interior angle= 165.6 deg.
This is never true. In a parallelogram, the diagonals will always bisect each other. Thus, each of these segments would always have to be equal.
Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the 
values in the table. In other words, we need to replace with each value in our given function and simplify.
- For x = 0
Since 
and 
, our first point is (0, -1)
- For x = 1
Our second point is (1, -4)
- For x = 2
Our third point is (2, -5)
- For x = 3
Our fourth point is (3, -4)
- For x = 4
Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
